alphanumeric characters). (Figure 2-65)

DTK:
Desired track is the Great Circle course in whole degrees between
the FROM and TOwaypoints from Navigation Page 1. (Figure 2-58)
If the system is displaying Direct To a waypoint, the DTK will be from
present position to the current To waypoint.
NOTE: If the default desired track is changed, a Pseudo Vortac
(selected course) leg will be programmed on the NAVIGATION 1/4
Page.
INTERCEPT Messages:
If the Intercept Mode is programmed one of the following messages
may appear. (Figure 2-65)
• INTERCEPT BEYOND FIX indicates the commanded heading will
cause the aircraft to intercept the programmed course on the FROM
side of the fix.
• NO COURSE INTERCEPT indicates the commanded heading will
cause the aircraft to diverge from the programmed course (crosstrack
deviation will increase).
• No Message indicates an intercept is not programmed, or the com-
manded heading will intercept the programmed course prior to the fix.
(The TO side of the fix)
• NO ARC INTERCEPT indicates commanded heading will not inter-
cept the arc programmed on the approach procedure.
